Eh...the only thing this review talks bad about is the dark scene in Harry Potter, a scene which is very extreme indeed. How does that scene look on any other LED TV? Let's see some comparisons to other manufacturers like Samsung with the same scene.
They also mention about the viewing angles, which is questionable. Other reviews I have read say the viewing angles on LG TVs outdo others easily. Those same reviews gave good marks for the black levels in comparison to other LEDs.
But, they like everything else about the TV.

This is only one review and the only one that gave the black levels low marks in one instance without comparisons, yet they also say the blacks look well in other situations.
Still looks like a good one to buy to me.
